The Durability of High-Strength Concrete Containing Waste Tire Steel Fiber and Coal Fly Ash

The demands for high-strength concrete (HSC) have been increasing rapidly in the construction industry due to the requirements of thin and durable structural elements. HSC is highly brittle. Therefore, to augment its ductility behavior, expensive fibers are used. These negative drawbacks of HSC can...
